-is received and discharged into the apartment after having been warmed.

It also consists in tubes, arranged in such manner that the foul air is drawn from the apartment and discharged into the chimney.' Y

The details of construction and arrangement will be fully described hereinafter.

In the drawings- Figure 1 is a perspective View of my invention;

Figure 2, a transverse horizontal section through line :t-x, fig. 3; and

Figure 3, a rear elevation.

To enable others skilled in the art to which my invention appertains, to make and use the same, I will now proceed to describe fully its construction and manner of operation.

A represents a stove, of any proper form and arrangement, which is provided with the usual requisites of dampers, Ste.

B represents an air-chamber, located beneath the stove, which is connected, in any proper manner, .by pipe, or otherwise, with the out-door air.

0 0 represent tubes, which, extending from chamber B, up the sides of the stove, either inside or' out, as may be desired, discharge into the chamber D, upon the top of the stove.

d represents a register in the top'of chamber D.

E E also represent tubes, which open at the bottom of the stove, near the floor.

These, extending upward, discharge into the stovepipe F, as shown.

In order that this arrangement may not interfere an intel nal pipe, F which connects with the fire-chamfar to secure a perfect draught.

It passes thence, up, through the tubes G, into the chamber D, from which it is allowed to pass into the apartment by means. ofithe-register [1.

By closing the register, no cold air is permitted to enter the room when there is no fire in the stove, or when the fire is being kindled.

The foul air is drawn from the apartment by means of the tubes E, and is discharged into the smoke-pipe, without interfering with the draught.

I am aware that a patent was granted to E. A. Hill, October 17, 1854, for a coal-stove, which is so con structed as to accomplish, substantially, the same result as mine; I therefore desire' to limit myself simply to my specific construction and arrangement of parts.

Having thus fully described my invention,

What I claim, and desire to secure by Letters Ratent of the United States, is-

The stove A, having the chamber B, tubes 0 C, chamber D, with register d, in. combination with tubes arranged in the manner described, for the purpose set forth.
